SILO-REINFOR QING-BOD ANCHOR.

Specification of Letters Patent.

Patented Feb. 15, 1921.

Original application filed May 22; 1917, Serial No. 170,297. Divided andthis application filed September 6, 1918. SeriaLNo. 252,811.

To all whom it may concern:

lie it known that I, tinonon P. Prunes, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements inbilo-Reinforcing-Rod Anchors, (division of my application Serial Number170,297,) of which the following is a specification.

This invention relates to silo reinforcing rod anchors and is a divisionof my application Serial Number 170,297 filed May 22,

I 1917. The present structure is designed for use in. connection with adoor frame suitably mounted withinthe silo structure itself andcooperative with the circumferential reinforcing rods to give a suitableanchorage at the ends of the latter to avoid passage over or through thedoor openings.

Particularly in cement block silo construction, the thicknesses of thevarious mortar joints may vary and, in this latter construction, thecircumferential reinforcing rods are usually embedded between twohorizontal roadways of blocks. It is essen tial that suitable anchors becarried by the door frame for securing the ends of these rods but theirexact location can not be predetermined because of the variations inthicknesses of mortar joints as outlined above and also due to thevarious distortions and shrinkages of the cement blocks themselves. Forthis reason, the main object of the present invention resides in astructure of anchor particularly adapted for the reception of the endsof these reinforcing rods and which may be so positioned and associatedwith the door frame that the various inequalities and distortions metwith in actual practice may be handily overcome. To this end, the anchoris of a peculiar form so mounted upon the door frame as to permit of itsproper adjustment and also constructed to accommodate lateral.adjustable connection of the min forcing rod ends.

The structure for accomplishing the foregoing is shown in theaccompanying sheet of drawings which represents the preferred embodimentof my invention. In these drawings, similar characters of referencedesignate corresponding parts throughout and,

of a cement b ook silo with the door frame Figure 1 re resents thepartial face view in its applied position, a portion of the frame andblock structure beingbrokcn away to clearly disclosethe anchorage forone end of a circumferential reinforcing rod, and j 1 Fig. 2 is afragmentary view in perspective showing the anchor attached to the doorframe and illustrating the reinforcing rod in broken lines.

In Fig. 1, the silo is shown as being built up of a plurality of blocks1, the mortar joints being shown by single lilies desig nated 2. Whilethe present invention is shown in conjunction with cementblocks, it isnot particularly limited to such application but is equally applicablewherever the types of adjustments already described are essentialproviding the reinforcing rods may be adapted to that particular type ofstructure.

The door frame is designated in its entirety by the reference numeral 3and its top and bottom and vertical edges are preferably in the form ofchannels as illustrated in Fig. 2 to embrace the silo structuresurrounding the door opening. The door frame is closed by means of thedoor a, the latter being drawn into proper holding position and latchedin such position by means of the latching structures designatedgenerally by the reference numerals 5 and 6 all as described and claimedin my application above referred to.

Between the inner and outer legs 7 and 8 respectively of the verticalportions of the door frame there are located the desired number ofanchors for the circumferential reinforcing rods 9, each of theseanchors cons1sts preferably of an angularly shaped member whoseverticalleg is designated 10 and whose horizontal leg is designated 11. Thevertical leg is provided with a vertically disposed slot 12 and isattached to the door frame by means of the bolt and nut structure 18. Aslot 12 in the vertical leg 10 of each member is made of a height topermit of the normal variations in the thicknesses of mortar joints byvarious workmen. It will be understood that should the thicknesses ofthese mortar joints vary, for inshould be and than could be accommodatedunless suitable adjustments are provided.

For this reason, either the upper anchors may be properly adjusted orthe door frame may be moved slightly vertically but permitting the loweranchors to remain in position and the entire structure then'drawn tightand in rigid holding relation. Each of these reinforcing rods havetheirends turned down at right angles as is illustrated at 14 and these endsare adapted to fit in slots 15 in the horizontal legs 11 of the anchors;This permits "of the necessary lat-- association of circumferentialreinforcing rods and the door frames. As stated, these clips merely formanchors for the ends of the reinforcing'rods to avoid passage over thedoor opening, the door frames themselves functioning as continuations ofthe. remforclng rods. The proper ad uStments such as may be caused bymortar joints of varying thicknesses and distortions to be found in theblocks from which the silos are made may be readily-accomplished. At thesame time the door frame structure may beinitially equipped with theseanchors and shipped in connection therewith.

What I claim is;

In a silo, a door frame, a reinforcing rod extending around the silo,angle members carried by the vertical sides of said frame between itsinner and outer edges, one leg of each member lying fiat against thatportion of the frame between its vertical sides and being provided witha vertical slot, and means for adjustably securing said members to saidframeby said slots, the other leg of each member being'disposedcrosswise between the sides of said frame and being provided with a slotextending crosswise between the frame sides for the reception of one ofsaid rod ends.

In testimony whereof I afiix my signature.
